Fluid inclusion services
Fluid inclusions are vacuoles sealed within minerals. When trapped within diagenetic and ore-forming minerals, they provide the only direct means of examining the fluids present in ancient geological systems.
They may provide the following valuable information with simple petrographic observations, microthermometric analysis, or sophisticated geochemical analysis of inclusions contents:
- Temperature of mineral precipitation
- Pressure of mineral precipitation
- Composition and origin of fluids of mineral precipitation
- Later history of temperature, pressure and fluid composition
- Improve understanding of diagenetic- and ore-forming systems
- Improve understanding of subsurface fluid evolution
- Improve interpretation of petroleum migrating history
Natural processes have provided:
- Constant volume
- Constant composition
